Most phones secured bootloaders are hacked in less than 6 months if there is sufficient interest in the model. So if treatment of this as a huge security threat that makes other rights moot is valid then most of us should be able to return our improperly secured phones before their warranty is up.
Not the case, it takes significantly longer... if it happens at all.
Much longer. It took until 2019 for checkra1n to become a thing to unlock Apple A7 to A11 devices. Apple A11 is a 2017 SoC.
A12, A13, A14 remain uncracked today.
In Android lands, bootloaders starting from quite some years ago are quite solid too, with no bypasses except when the device maker provides you the possibility to unlock it.
None of which is relevant to the premise that someone is going to do [insert something evil here - perhaps involving the radio]. Because if any device is cracked after any period of time then someone wanting to do [insert something evil] will just buy that device in order to do it.
